ルギーを図つて経済運転を行えるものである。As explained above in the embodiments, the first invention provides power to a dual fuel engine that can be operated with storable fuel such as petroleum or gas fuel that can be constantly supplied such as city gas supplied through a fuel switching device. A compression-type air conditioner and heater are connected to a generator via a switching device, and the engine is normally operated mainly using gas fuel to drive the air conditioner, thereby providing air conditioning or heating, and storing it in case of an emergency. Since the engine is configured to be able to drive the generator by operating the engine with the storable fuel, it is relatively easy to use in the case of normal cooling or heating operation with a long operating time. The engine can be operated economically using gas fuel that is in good and stable supply conditions, and in the event of an emergency when the gas fuel supply is restricted or stopped, the engine can be operated using the same storable fuel such as stockpiled oil. It can generate emergency power, reducing equipment costs and operating costs compared to conventional systems in which the heating and cooling drive unit and the engine-driven emergency power generator were set separately and operated by separate means. It has now become possible to reduce the Further, the second invention further provides a heat exchanger in the exhaust system of the above-mentioned air conditioning and heating engine and emergency power generation engine, and uses a part of the exhaust heat recovered here as a heat source for heating and cold absorption type air conditioning. Therefore, economical operation can be achieved with further energy savings.
